Starting from the AV Room, you can immediately grab the Fireworks Remote, then head over and pacify Harry, making sure not to be spotted by AV Crew up the hall. Drag him into the office to his left. No one goes in here so he shouldn't be found.

Using the stairwell that has a lone AV Crewman, immediately head to the basement and pacify Marv. If timed right, he should not yet have grabbed the Coconut. It is best to grab the coconut first, as it will break if he drops it when you attempt to pacify him, and you may not get credit for the challenge. If you take too long and he grabs the apricot, it too may break when dropped.

If you can get to the basement in time, Marv may still be in the hallway outside the Cafeteria. If you can pacify him here, out of sight, you can leave him since no one will find him there. You can also drag him to the Catacomb Stairwell.

It is not known if the challenge will succeed if other items are dropped by the bandits when you pacify them and pick the items up. Therefore it is safest to get all the items yourself first.

Harry "Smokey" Bagnato (upstairs 2F/3F) Theft Items:

• Fireworks remote (AV Room starting point)
  
• Circumcision Knife (Library)
  
• Saber (Attic)
  
• Microphone (Attic)
  
• Cowboy Bust (Attic, above Museum Director's Office)
  
• Bust (Attic/Cicada Security Control desk)

Marv "Slick" Gonif (Bsmt/1F) Theft Items:

• Coconut (Basement Cafeteria; do not let Marv get it)
  
• Apricot (Basement Kitchen; do not let Marv get it)
  
• Cannonball (Museum)
  
• Toy Tank (Gift Shop)
  
• Battle Axe (Bar)
  
• Shuriken (Backstage Hall Clothing Rack)

Note: the first time you complete the mission you'll unlock the suit as a starting outfit, however this increases the difficulty significantly since you'll have to change out of it in order to safely access other areas. It is recommended to NOT use this option.

It is best to complete the first section, getting the loot items, before attempting to get the santa suit since timing will be critical if and while Harry and/or Marv are awake and looting.

To get the suit, you'll need to find Santa pacify/kill him, take the suit, and ideally change back out of it somewhere near the final location (basement wine room or outside Lion fountain).

Recommendation: use the stairs to and from the basement kitchen, lure a chef or other staff near to the Wine Tasting Room, hide them in the Catacombs Exit stairwell, and change outfits there. This also the best place to wait for Harry and Marv to meet for the 'Oh, Deer' challenge.

To find the suit, you'll have to encounter Santa randomly. If you use the AV Room starting point, Santa will very often appear in the nearby Dining Room at about 2 minutes from starting the mission.

You can find Santa by listening for the jingling bells, and looking in the closest "Santa Spawn" locations, listed below.

Santa Spawn Locations

First Floor

• Hallway between Entrance Hall and Catwalk
  
• Bar
  
• Pagoda Garden (Nabokov/Dexter Meeting Spot)

Second Floor

• Dining Room
  
• Library

Third Floor

• Attic Chamber
  
• Cicada Security Control
  
• Voltaire Suite Bathroom
  
• Auction Room Balcony

Basement

• Locker Room
  
• Wine Tasting Room

First, you'll need to find a Propane Flask, of which there are several throughout the Basement and First Floor. The most convenient and recommended location is the hallway between the Wine Cellar and Cafeteria. There are others in the Shed between the VIP Parking Area and South Garden, at the base of the Three Lions Fountain, the Shed near the Barge Stairwell, and the first floor Kitchen.

To complete the challenge, the following conditions must be met:

1. Harry and Marv must both fail to steal any and all 12 items, and while not known if specifically required, these 12 items should be in your inventory.

2. Harry and Marv must be together in the same place *after* they give up their quest, which only occurs in 3 places (see below).

3. They must be killed *simultaneously* by the same Propane Flash explosion trap.

4. You must be wearing the Santa suit at the moment they are killed.

The absolute best place to set the trap is the "tarp" in the Wine Tasting Room. While the challenge thumbnail shows the Lion Fountain, this is a very tricky spot to spring the trap, and not recommended.

The tarp is a white painters' cloth on the floor in the Wine Tasting Room in the basement. After they give up their search for loot, they'll eventually congregate in the Wine Tasting Room for a Christmas toast and will stand on the tarp for several seconds.

Note that it takes a LONG time for them to come together, as they will search the *entire* house for loot. They may go outside to the Lion Fountain after the toast but will come back to the tarp if they do.

The best way to set and spring the trap is to throw the Propane Flask anywhere which will cause it to leak. You can then pick it up and place it carefully on the tarp, ideally away from the middle.

You'll want to wait in the Catacomb Stairwell out of sight in the Santa Suit. Note that if either of them sees you, they'll panic and scatter and you'll have to wait for them to calm down to come back.

Once they're in position, the best way to set the trap is to shoot the ground near the Flask or the Flask itself.

The Catacomb Stairwell is also convenient for exiting the mission as it is very close to this spot.
